Methods of measurement for radio transmitters -- Part 3: Wanted and unwanted modulation -- Supplement 1: Appendices - Supplement 2: Unwanted modulation, including hum and noise modulation

Describes the conditions and methods of measurement for assessing the performance of transmitters with respect to wanted and unwanted modulation. The methods of measurement described are restricted to those properties that may be liable to ambiguous interpretation due to the application of different methods and conditions of measurement and are intended for type tests and acceptance tests but may also be used for factory tests.

Méthodes de mesure applicables aux émetteurs radioélectriques -- Partie 3: Modulation utile et modulation parasite -- Complément 1: Annexes - Complément 2: Modulation parasite

Décrit les conditions et les méthodes de mesure pour relever les caractéristiques relatives à la modulation utile et parasite d'un émetteur radioélectrique. Les méthodes de mesure décrites sont limitées aux caractéristiques qui pourraient être l'objet d'interprétations équivoques en raison de l'utilisation de méthodes et de conditions de mesure différentes. Elles concernent aussi les essais de type et les essais de réception; elles peuvent aussi être employées pour les essais de contrôle en usine.
